+# SHA-1 engine
+See a []( for the full git history of this code. Branch name is submission-mpw-two-c.
-Refer to [README](docs/source/index.rst) for this sample project documentation. 
+This is an implementation of [](RFC 3174) of SHA-1 engine.
+It is not the most secure one nowadays (it is still used for git commit ids and TPM PCR values), but
+it looked like the easiest of the SHA engines to implement. The communication channel is via
+WishBone commands to provide sixteen words after which the engine starts and computes the digest
+in about 160 cycles. Then digest can be retrieved via the wishbone. There is a IRQ line so when
+it has completed it will bring it high if that is enabled.
+If you want to see this more interactively, I would recommend you clone
+[]( and run
+make test_wb_logic
+which will use the various WishBone commands to program it.
